1Preheat your oven to 220°C (428°F).
Roll out the pizza dough on a floured surface to your desired thickness.
Spread the tomato sauce evenly over the rolled-out dough, leaving a small border around the edges.
Sprinkle the mozzarella cheese evenly over the tomato sauce.
Distribute the sliced onion and sliced bell pepper evenly over the cheese.
Place the pizza in the preheated oven and bake for 12-15 minutes, or until the crust is golden brown and the cheese is bubbly.
Remove the pizza from the oven and let it cool for a few minutes before slicing and serving.
